source for anti-HLA Class I mAb or hybridoma?

[Henry Needham]

I was wondering if anybody could tell me the sources for anti-HLA Class I
monoclonal antibodies or hybridomas that produce them (preferrably).  I 
have tried the ATCC catalog, but many of them were not there (e.g., A1, 
A9, A11 etc).

Your suggestions are most appreciated.
